Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a hinge switch that is applied to, for example, a starter switch/headlight switch provided on the handlebar of a motorcycle.

[Prior Art] Conventionally, for example, a motorcycle's starter switch and headlight switch (for switching power) are:
Separately attached to the handle. Since the starter switch is for switching large currents, it is a push button switch with sufficient contact distance, while the headlight switch does not require a large contact distance and is generally a slide switch.

By the way, these are provided separately,
For battery circuits, on and off are in an inverse relationship with each other, and by integrating them, it is possible to reduce the number of switches.

[Problems to be solved by the invention] However, in slide switches generally used for switching multiple circuits, the distance between the contacts must be large for switching large currents, resulting in a large stroke. On the other hand, push button switches have a short stroke but can only open and close one circuit, which limits their use. The present invention was devised in view of these circumstances, and the purpose is to provide a hinge switch that can be used as a multi-purpose switch that can also switch large currents and switch multiple circuits because it can provide a sufficient distance between the contacts. do.

[Means for Solving the Problems] The hinge switch of the present invention has a switch arm provided in a case so as to be rotatable by a push button, the switch arm being biased by a spring in the direction of repulsion of the push button, A plurality of movable contacts are provided at different rotation radius positions, and each movable contact is configured to contact the plurality of fixed contacts provided in the case in two types of contact structures: normally open and normally closed. It is characterized by having been.

[Operation of the invention] According to the invention, for example, one contact part can be used as a starter switch, and the other contact part can be used as a headlight on/off switch. That is, due to the advantage of the hinge switch in that the distance between the contacts is large, it is possible to combine a plurality of switches for switching between large and small currents, and since the switching can be reversed, it is possible to turn one switch on and the other switch off.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings. The hinge switch of this embodiment is a headlight switch that also functions as a starter switch and is installed on the handlebar of a motorcycle.

As shown in FIG. 1, a switch arm 2 is provided in a case 1 so as to be rotatable by a push button 3. As shown in FIG. Reference numeral 4 indicates its fulcrum shaft, and 5 indicates a bracket for supporting the fulcrum shaft. The switch arm 2 is biased by a torsion spring 6 in the direction of repulsion of the push button 3.

The switch arm 2 has a pair of movable contacts 7, 8 at different rotation radius positions. Each movable contact 7, 8
The directions of the contact surfaces are opposite to each other with respect to the rotation direction. A pair of fixed contacts 10 and 11 are attached to the bracket 5 via a fixed arm 9.
are provided corresponding to the contact surfaces of the movable contacts 7 and 8, thereby forming two types of switch parts 12 and 13: normally open and normally closed. Each of the switch sections 12 and 13 is connected to a battery circuit (not shown), with the normally open switch section 12 serving as a starter switch and the normally closed switch section 13 serving as a headlight switch (for switching power supply). In addition, the normally closed switch part 13
As shown in FIGS. 2 and 3, the switch has a two-pronged switch structure.

When the push button 3 is pressed, the normally open switch section 12 is closed, as shown in FIG. 4, and a starter switch (not shown) is activated. At the same time, the normally closed switch section 13 is opened, and the headlight circuit (not shown) is disconnected from the battery. 5 and 6 show how the normally closed switch section 13 is switched from closed to open.

According to the configuration of the above embodiment, one push button switch can serve as both a starter switch and a headlight switch. Further, the distance between the contacts necessary for a large current switch can be sufficiently secured based on the hinge switch structure. Therefore, for example, both switches can be installed on the handlebar of a motorcycle at once, providing the advantage that both operations can be performed simultaneously without taking one's hands off the handlebar.

In addition, in the above embodiment, the number of contacts was 2, but
Of course, it can also be implemented with 3 or more. It goes without saying that the present invention can also be applied to various switches other than the motorcycle switch described above.

[Effects of the Invention] According to the present invention, it is possible to provide a multi-function switch which can switch a plurality of circuits and can also switch a large current, although the stroke can be made relatively short.
